Roger Federer undergoes knee surgery to repair torn meniscus

Roger Federer underwent knee surgery Tuesday to repair a torn meniscus, he wrote on his Facebook page Wednesday.

Federer sustained the injury the day after losing in the semifinals of the Australian Open to Novak Djokovic, and the recovery process will require him to miss the World Tennis Tournament in Rotterdam and the Dubai Championship.

“I apologize to my friends in Rotterdam and Dubai, as I was very much looking forward to playing those events,” Federer wrote. “While this is an unfortunate setback, I am encouraged and grateful that my doctor said the procedure was a success. I am looking forward to attacking the rehabilitation process this afternoon with my team and working hard to get back out on tour as soon as possible.”
